Find The Measure Of An Exterior Angle Of A Regular Polygon Of 9 Sides. To find the measure of one angle the formula is 360n where n is the number of the sides of the polygon. Ex 32 2 Find the measure of each exterior angle of a regular polygon of i 9 sidesWe know that Exterior angle 360𝑛 where n is the number of sides of regular polygon Given Number of sides of a regular polygon 9 Exterior angle 360 9 40 Ex 3.
The exterior angles have a sum of 360 572. Since frac360940 Exterior angle40 degrees for polygon of 9 sides. Allow s to represent the number of sides of the polygon.
This tutorial the shows how to find out the measure of an exterior angle of a regular polygon.
Consider the following parallelograms. Each exterior angle of a regular polygon of 9 sides n360o where n 9 9360o o 40o. Sum of all exterior angles of given polygon 3 6 0 i Measure of each ext angle 9 3 6 0 4 0 ii Measure of each ext angle 1 5 3 6 0 2 4. Find the measure of each exterior angle of a regular polygon of i 9 sides ii 15 sides.
